 The Cosmos-SDK is a framework for building blockchain applications in Golang.
 It is being used to build `Gaia`, the first implementation of the [Cosmos Hub](https://cosmos.network),
 
 **WARNING**: The SDK has mostly stabilized, but we are still making some
 breaking changes.
 
+**Note**: The `master` branch is an active development branch. For the latest
+release, see the [release page](https://github.com/cosmos/cosmos-sdk/releases).
+
 **Note**: Requires [Go 1.10+](https://golang.org/dl/)
